For thousands of years, people have used their planet for selfish purposes. Cities and factories were built, tons of coal, gas, gold, oil and other materials were mined. At the same time, man himself destroyed in a barbaric way and continues to destroy what nature has given us. Thousands of innocent birds , insects, fish perish through the fault of people; the number of endangered species of animals is constantly increasing; destroyed by thousands of hectares of forest , etc. Soon, a person can experience the wrath of mother nature in their own skin. It will be about global warming, which is gradually coming to our land. A person is already beginning to experience the consequences of this cataclysm. It will turn into a tragedy for both man and all living things on our planet. Nature is able to live without man. It changes and evolves over the years, but man cannot survive without nature and its resources .

What is global warming?
Global warming is a gradual and slow increase in average annual temperature. Scientists have identified many causes of this cataclysm. For example, volcanic eruptions , increased solar activity, hurricanes, typhoons, tsunamis, and of course human activity can be attributed here. The idea of human guilt is supported by most scientists.
Causes of Global Warming
Many people already know that global warming is one of the major issues today. It is worth considering that there are such factors that activate and accelerate this process. First of all, the negative effect is exerted by an increase in the emission of carbon dioxide, nitrogen, methane and other harmful gases into the atmosphere. This occurs as a result of the activities of industrial enterprises, the operation of vehicles, but the greatest environmental impact occurs during environmental disasters : industrial accidents, fires, explosions and gas leaks.
The acceleration of global warming is facilitated by the release of steam due to high air temperature. As a result, the waters of rivers, seas and oceans actively evaporate. If this process is gaining momentum, then for three hundred years, the oceans can even significantly dry out.
Since glaciers melt as a result of global warming, this contributes to an increase in water levels in the oceans. In the future, it floods the coasts of continents and islands, and can lead to flooding and destruction of settlements. During melting ice , methane gas is also released, which significantly pollutes the atmosphere .
Global warming factors
There are also such factors, natural phenomena and human activities that contribute to slowing global warming. First of all, ocean currents contribute to this. For example, the Gulf Stream slows down. In addition, a decrease in temperatures in the Arctic has recently been noticed. At various conferences, problems of global warming are raised and programs are put forward that should coordinate the activities of various sectors of the economy. This reduces the emission of greenhouse gases and harmful compounds into the atmosphere. Consequently, the greenhouse effect is reduced, the ozone layer is being restored, and global warming is slowing down.
The effects of global warming
- First of all, this is an increase in average temperature. Every year, the average annual temperature rises. And every year, scientists observe that the numbers of elevated temperature are rising;
- Melting glaciers . Nobody argues here. The cause of the melting of the glaciers is indeed global warming. Take, for example, the Uppsala glacier in Argentina, whose length is 60 km, width up to 8 km, area 250 km 2. Once it was considered one of the largest glaciers in South America. It melts two hundred meters annually. And the Rowan glacier in Switzerland climbed four hundred and fifty meters;
- Sea level rise. Due to the melting of glaciers in Greenland, Antarctica and the Arctic and warming, the water level on our planet has risen by ten to twenty meters and is gradually increasing annually. What awaits our planet as a result of global warming? Warming will affect many species of animals . For example, penguins, polar bears and seals will be forced to look for a new place to live, as their natural habitat will simply melt. A lot of representatives of the animal and plant world will disappear due to the fact that they will not be able to quickly adapt to the new habitat. An increase in the frequency of natural disasters is also expected.
A large amount of rain is expected, while in many regions of the planet drought will prevail, the duration of very hot weather will also increase, the number of frosty days will decrease, the number of hurricanes and floods will increase. Due to drought, the amount of water resources will fall, agricultural productivity will drop. It is very likely that the number of forest fires and burning on peat bogs will increase. Soil instability will increase in some parts of the globe, coastal erosion will increase, and the area of ice will decrease.
The consequences are of course not very pleasant. But history knows many examples when life won. Remember at least the Ice Age. Some scientists believe that global warming is not a global catastrophe, but just a period of climatic changes on our planet that occur on Earth throughout its history. People are already making efforts to somehow improve the condition of our land. And if we make the world a better and cleaner, and not vice versa, as we did before, then there is every chance of surviving global warming with the least loss.
